Yes. Grok makes video through Grok Imagine, using the Grok Imagine Video 1.5 model, and xAI’s documentation lists clips up to 15 seconds at up to 1080p.
That 1080p figure has a catch, though. It doesn’t apply to every video workflow.
Free access has its own catch. Trackers say free Grok accounts lost video generation on March 19, 2026, but xAI hasn’t published a consumer free-video quota.
What is the difference between Grok Imagine and Grok Imagine Video 1.5?
Grok Imagine is xAI’s image and video generation experience. You reach it on grok.com, in the Grok apps, and through the API.
grok-imagine-video-1.5 is the video model underneath. xAI’s pricing page also lists an older grok-imagine-video model and a cheaper grok-imagine-video-1.5-lite.
Is Grok video generation free in 2026?
Don’t assume it is on the official service. The sources disagree, so here is who says what.
What does xAI say about free video?
xAI’s own documentation confirms the video model and what it can do. However, it says nothing about a free video quota for consumer accounts.
What do trackers report?
Several trackers report that free video ended on March 19, 2026, after earlier restrictions on Grok’s image generation. They split on whether limited free video came back later, and nothing from xAI settles it. Test your own account before you rely on either claim.
Is there a free third-party option?
Yes, but it isn’t a Grok free tier. fal.ai advertises five free Grok Imagine Video 1.5 Lite image-to-video generations per 24 hours for signed-in users.
That offer belongs to fal.ai, not xAI, so it can change without notice. It also runs the Lite model, which means you shouldn’t expect the output of full Video 1.5.
How do you generate a video with Grok Imagine?
Open grok.com/imagine, or the Imagine tab in the Grok app, and sign in. If your plan includes video, pick video mode, add a prompt or an image, and generate.
- Open grok.com/imagine or the Grok app.
- Switch to video mode.
- Type a prompt, or upload a still image to animate.
- Generate, then check the motion and the audio together.
- Download the clip, or extend it.
What should the prompt say?
Write the prompt around motion, camera, and sound. Here are three examples:
- Image-to-video: “Slow dolly-in on the mug as steam curls upward; a spoon clinks softly in the background.”
- Text-to-video: “Handheld shot following a cyclist down a wet neon street at night, rain hitting the pavement.”
- With references (API): “
<IMAGE_0>turns to the camera and greets the room in the voice from<AUDIO_0>.”
What can Grok Imagine Video 1.5 do?
Grok supports 1080p, but not in every workflow. In fact, xAI’s documentation sets different limits for generation, references, editing, and extension.
Which workflows support 1080p?
Only text-to-video and image-to-video reach 1080p. Everything else drops to 720p, so check the table before you plan a project.
| Workflow | What it does | Limits in xAI’s docs |
|---|---|---|
| Text-to-video | Builds a clip from a prompt alone | 1–15 s, up to 1080p |
| Image-to-video | Uses your image as the opening frame | 1–15 s, up to 1080p |
| Reference-to-video | Guides a clip with up to 7 reference images and up to 3 preset voices | Up to 15 s, 720p max |
| First and last frame | Pins the opening and closing images | Documented under reference-to-video |
| Keyframes | Pins up to 4 images inside the clip | Placed on a 1/3-second grid |
| Video editing | Modifies an existing clip | Output capped at 720p; edited clips keep the original length, capped at 8.7 s |
| Video extension | Continues a clip from its last frame | Adds 2–10 s; output capped at 720p |
How do the pinning tools differ?
Each tool solves a different problem. Reference images bring a person, product, or outfit into a clip without locking the first frame, while image-to-video does lock it.
First and last frame fix where a clip begins and ends. Keyframes, on the other hand, fix up to four moments in between, so choose by how much control you need.
How does video extension work?
Extension takes input clips of 2–15 seconds and adds 2–10 more. Because of that, one pass tops out at 25 seconds.
How does audio work in Grok video?
Sound comes built in, since clips carry an audio track by default. API users can turn it off with generate_audio=false.
Voices come from a preset roster. Your own audio as a voice reference, however, is limited to trusted partners on request.
How does text-to-video build a clip?
For text-to-video, xAI’s docs say the model generates a first frame from the prompt, then animates it. If you need a specific composition, start from your own image instead.
Does your plan include every workflow?
Not necessarily. The table comes from API documentation, so your plan may not include every workflow yet.
xAI’s August 1 post said the newest video features reached SuperGrok Plus and Heavy subscribers first, then rolled out to every tier over the following days. That post is two months old, though, and one independent write-up describes text-to-video and 1080p as broadly available on web, iOS, and Android. For that reason, check your own plan.
Also, the editing and extension examples in the docs use the older grok-imagine-video model. Confirm which model a workflow runs before you build on it.
What are Grok video’s real limits?
xAI documents the technical limits and leaves the consumer quotas blank. Mixing the two up causes most of the confusion in older guides.
Which limits does xAI document?
A generation runs 1–15 seconds. In addition, reference-to-video allows up to 7 images, 3 preset voices, and 4 keyframes.
Reference-to-video, editing, and extension all cap at 720p. Extension adds 2–10 seconds to a clip that is 2–15 seconds long.
Which limits does xAI leave unpublished?
Daily and weekly consumer allowances are missing, and so are per-tier video quotas. xAI also hasn’t said whether quotas shift under load.
Trackers fill the gap with conflicting numbers. One claims a single weekly usage pool replaced separate daily limits in June 2026, but nobody has confirmed that.
What happens when moderation blocks a clip?
Moderation adds friction too. Grok can block a request with a video moderated message.
Some users also report generations stalling near the end, followed by an error calling moderation service message. That pattern comes from user reports, so treat the cause as unconfirmed.
How much does Grok video cost?
Consumers pay by subscription, while developers pay per second of output. Both move often, so the consumer prices below carry a date.
What do the consumer plans cost?
The iOS App Store listing for Grok shows SuperGrok Lite at $10 a month, SuperGrok at $30, and SuperGrok Heavy at $300. I checked that listing on October 8, 2026, and prices can differ by platform and region.
Trackers put SuperGrok Plus at about $100 a month. No official page confirmed it, so treat that figure with caution.
What does the API cost per second?
The API is simpler. For grok-imagine-video-1.5, xAI publishes $0.08 per second at 480p, $0.14 at 720p, and $0.25 at 1080p, plus $0.01 per input image.
| Clip length | 480p | 720p | 1080p |
|---|---|---|---|
| 5 seconds | $0.40 | $0.70 | $1.25 |
| 10 seconds | $0.80 | $1.40 | $2.50 |
| 15 seconds | $1.20 | $2.10 | $3.75 |
The 1080p column covers text-to-video and image-to-video only, because reference-to-video stops at 720p. The Lite model costs $0.02 per second at 480p, $0.03 at 720p, and $0.14 at 1080p, and it takes text and image input.
What does an API request look like?
A basic request is a JSON body sent to https://api.x.ai/v1/videos/generations:
{
"model": "grok-imagine-video-1.5",
"prompt": "Timelapse of a flower blooming in a sunlit garden",
"duration": 10,
"aspect_ratio": "16:9",
"resolution": "720p",
"generate_audio": false
}The response returns a request_id. Poll https://api.x.ai/v1/videos/{request_id} until the status reads done, and remember that leaving out resolution gives you 480p.
These numbers price generation, not a finished video. Even flagged generations cost money, because xAI’s pricing page says it still bills requests that break its usage guidelines.
Who should use Grok Imagine Video 1.5?
Short clips, animated stills, and shots built from reference images suit it best. Built-in audio and fast iteration help with social content.
Skip it for long scenes or for jobs that need 1080p in every workflow. It won’t handle captions, branding, or publishing either, so plan a separate editing step.
Clip length isn’t the selling point, since 15 seconds is modest. Instead, reference control, short clips, and built-in audio together make the case.
